Reeves' OMNI GLH-R Update!

[Reeves]

I'm gonna call these guys.

http://www.passonperformance.com/

Wow...this guy is kind of a dick....but very informative!

He said that cutting every other dog off the gear, and every other groove out of the slider may help, but just doing the gear wouldn't do anything, and doing the brass was total non-sense. He said if you only did the slider, it would be more benefit than doing anything else. Hmmm.....

After explaining as much as I could over the phone with him, he suggested that it is a pressure plate issue that was causing my missed 2nd shift and that caused my dogs on 2nd gear to round off. Asked me if I had centrifugal rollers on my pressure plate. Then said I need them?

He gave me some other people to call and talk to.

Hmmm......this is getting deep.

This is getting pretty deep. Centrifugal rollers on the PP? Interesting.

We could easily double up the springs on each side of the synchros in our transmissions. May be worth a shot?

I'm not sure I see how this would work in getting a more positive engagement. Even with extra spring, you still have to engage the dogs to engage the gear.

Working off of memory here, so I could be missing something....

Here is the logic behind it from the DSM thread.

The springs in the hub push the keys outward against the slider. The keys rest on the slider and move with the slider as you shift gears. When you shift gears the keys mate with the synchro ring and push the synchro ring onto the cone of the gear as you shift toward that gear, this is what matches the gear speed to the slider speed and prevents that gear grinding noise you may hwear with worn synchros. The keys are free to move up and down on the slider but the pressure exerted by the springs keeps the key movement some what in line with the slider movement. The stronger the force exerted on the keys outward toward the slider the more the keys will move with the slider and press against the synchro which mates with the cone on the gear. If you run two springs on each side of the hub instead of one it can help high RPM shifting, the only downside is that shifting 1 and 2 may be a bit more notchy, but not much at all, it was hardly an issue for me.

Look, just put the automatic back in it and get over this 5 speed crap.....

JFWY!!!

AND: Remember the shifter cable bushings needed some help too....

Why do you have oil in your throttle body?
.

Too much blowby, oil was getting into the intake system so with boost, it would push it out the TPS,

Ouch. Good Luck on the good gearset... hard to find. I have seen "freshly rebuilt" transaxles with fresh brass rings and worn dogs on the gears, this seems to be common practice?

Because unless you have a stash of good gears, your SOL.

I seem to recall it being posted that the service limit for the gears is more than half the dogs worn off. It they've been rounded half way they are technically still good go go.

I was taught that when the point is gone, they are junk as it won't catch the synchro properly. Maybe that's changed? I do know my friends IROC had rounded off teeth and would grind, replaced it and fixed.

What's the disadvantage to going the "crash box" route? Any?

JUst do second and third others not really necessary. Only disadvantage I've seen is going on and off the gas while in gear little sloppy.
do it! you'll like it.

[Rampage16V]

James if you have a part number I have a couple new gears here but not sure what trans they are for. And jt I have a basket full of 568 parts

[BadAssPerformance]

PM me How much?...

I'm still confused on this theory. You are ONLY cutting every other dog off the brass synchro stop ring, and the synchro teeth on the gear itself....correct? NOT doing anything to the slider? I don't see how it would be anymore sloppy this way? Maybe I'm just not getting it yet.

Here's something interesting I found out last night. The trans I'm currently running has 1 synchro tooth missing in 3 different spots on 2nd gear. Not broke off or warrened off, they weren't there to begin with. The trans I broke a while back, has ALL the synchro teeth on 2nd gear. Andy's 555 which I just tore apart last night has 1 synchro tooth missing in 3 different spots, just like my current trans. Anyone noticed that before?

Hmmm.....I don't remember there being any part numbers on it...but I do remember some markings. Got any pics of what you got? Definiately interested!!!

Pics coming soon.

[Reeves]

My thinking is the heavy disc is acting like a flywheel and not slowing down soon enough.


And my thought on the springs is that they are causing chatter with super grippy friction material.


Pics of Andy's main shaft with little wear on the synchro teeth. I'm going to have to get my better camera for pics like this. I have a garage camera that isn't so good:

I've seen sliders like that before. I've actually seen both types. If I have both out of transmissions right now I will try to take some good pics and post them up.

I think your idea about grinding a little off the stop for second gear will work well.

Mr. Passon offered a service to weld and remachine the dogs for the 833 four speed. I don't know the cost or if he could do the same for your 555 gears. It might be worth another call.

He didn't seem to interested without big $$$ for tooling.

Figured.

Trans back in. Pics later.

Cheap Harbor Frieght bearing separator kit. I got tired of borrowing my buddies separator all the time. Like DJ had mentioned, a 3" separator doesn't come with long enough bolts. I had some all thread laying around.



Andy's 555 that was in my building that I was supposed to be rebuilding.....instead of stealing parts from it His dogs on 2nd are worn, but not worn out like mine.




Don't buy cheap tools....


Go borrow your buddies Snap-On (again and again):


Andy's 2nd gear.....definitely worn, but not NEAR as bad as mine.


Random pics of both mine and Andy's main shafts dissassembled:

[BadAssPerformance]

Do you wear your SDAC badges? I seem to forget where I lose them the first or second night partying

[cordes]

Reeves, did the bolts just bend, or did the tool actually break? I was able to barely use the bolts which came in the kit I purchase from HF.
